2011 BMW 528i
Just did my update today for under $100. It's real easy. Find the map on the web. For the newer cars like mine you can only update via USB card using the port in the glove box. DVD's will not work. You will need to find a activation code.
I put a 10amp battery charge on. Turned ignition on . Put flash card in . Go to nav-options and software update page pops up in 15-60 sec. Enter activation code, about 50mins to install.
